The side walls on the 88's are very thin compared to "stock" pistons.  They
have to be in order to fit the case without machining.

Consequently, with less metal to transfer the heat there is a greater
tendency to overheat and distort.

Would someone explain to me what is wrong with the slip in 88s.I don't think

it would be because of a cooling problem.What is is?
   A" mild"cam should give you good power thru the low to mid RPM 
range.Don't use a radical cam unless you are going to keep the wick turned 
up. My.02.
